"Spill the Wine, Dig that Girl!" no, wait...?

I went to dinner at a restaurant called Spill the Wine last night, so I now have this song stuck in my head! Here is the original version I used to hear on the radio. And here is a live performance, with Eric Burden on vocals and the great band War playing a cha-cha groove with that wacky flute ("All Day Music" is still one of my favorite songs)

But ever since I heard it in 1970, I've been singing "spill the wine, dig that girl!" and it turns out that it is "spill the wine, take that pearl"? Talk about mondegreens!
